Application filed May 3, 1921.

To all whom it may concern:

Be it known that I, MARIANO J. SALAs, a citizen of the United States, residing at Molo Iloilo, Philippine Islands, have invented certain new and useful Improvements in Adjustable Sole Plates for Plows, of which the following is a specification.

This invention relates to new and useful improvements in adjustable sole plates for plows.

The principal object of the invention is the production of simple and economical means, wherebv the life of a plow may be materially prolonged.-

A further object is to provide means whereby the plow may be closedto run evenly and whereby the point of the plow share may be efiiciently braced by the adjustable sole plates.

With the foregoing and other objects in view, thatwill readily appear, as the nature of the invention is better understood, the invention consists. in the novel features of construction, combination and arrangement of parts illustrated in the drawing and particularly pointed out in the appended claim.

In the drawing Figure 1 is a side elevation of a plow with the sole plate detached therefrom,

Figure 2 is a similar view, parts being broken away showing the sole plate. in, one

position,

Figure 3 is a similar view showing the sole plate 1n another position, and

Figure 4 1s a section taken on the line 44 of Figure 1.

In the embodiment illustrated, the numeral 1 designates the plow beam which may be of any conventional construction and is attached to the handle members 2 which converge toward their mid portions as is usual and their lower portions extend parallel with each other. The lower portion of these plow handles? 2 are curved forwardly as is shown at 3. A post 4 connects the end of the forwardly extending portion 3 with an intermediate portion of the plow beam 1. The upper end of this post 4 is curved over upon itself and receives'the plow beam ltherebetween and is fixed there to by means of the bolt 5. A brace 6 is attached at each end to the mid portions of the post 4 and handle members 2. The plow proper is indicated by the numeral 7 and consists of the usual l' ll0ld:b0 t1'd 8 and a Specification of Letters Patent.

plow share 9. Upon the under surface of this plow 7 there is provided a web 10 having an aperture 11. This plow-share 9 is provided with the usual point and it is the purpose of the present invention to brace this point so as to protect same and prevent it from becoming bent when the plow is passing through very hard or roclq soil.

A sole plate 12 or runner is provided with a series of apertures 13 which are arranged so that each series will extend diagonally across the .sole plate as is clearly shown in Figure 1. The forward end of this sole plate 12 is inclined or beveled as indicated at 14 and is adapted to fit snugly under the plow share 9 so that its lower point 15 will be situated in close proximity to the point 16 of the plow share 9. The upper'apertures 13 will be engaged by the bolts 17 which pass through the forwardly extending curved portion 8, post 4: and web 10 as is shown in Figure 8 when the sole plate 12 first assembled in conjunction with the plow. As the point 16 wears it will readily be seen that this sole plate may be adjusted by placing the bolts 17 in the lower apertures 13. It will, of course, be understood that there may be as many apertures 13 as may be desired in each series. A guide plate 20 is fixed to the rear end of the sole plate 12 by means of the bolt 21 and aids in keeping the plow going straight or in alignment with the furrow already dug.

By the construction illustrated and described, it will be readily perceived that the sole plate may be adjusted to compensate for wear and to cause the plow to run level at all times and the plow point will be efiiciently braced so as to prevent it from becoming bent or unduly blunted.

From the foregoing description taken in connection with the drawing it is thought that the construction and operation of the invention will be understood without requiring a more extended explanation. It is of course understood that numerous changes in the mechanical construction of this invention may be made as may fall Within the post, a brace interposed between the midportions of the post, and the handles, a plow attached to the post, a soleplate adjustably attached to the plow and to the post and handles so as to have its forwardendsituated adjacent the plow point for bracing same.
